I think this is the answer
Answer:
.
Step-by-step explanation:
...
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
If I got it right it is 9.59166305.
Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Now plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em>, since it is much swifter that way. It does not matter which ordered pair you choose:
7 = 4 + b
If you want it in <em>Standard Form</em>:
y = 4x + 3
- 4x - 4x
_________
_______________________________________________
−5 = 4[−2] + b
−8
If you want it in <em>Standard Form</em>:
y = 4x + 3
- 4x - 4x
_________
** You see? I told you that it did not matter which ordered pair you choose [as long your <em>rate of change</em> is correct] because you will ALWAYS get the exact same result.
